PROPERTIES OF VOLUME HARDENED RAILS (WITH HARDNESS ON THE ORDER OF 331 TO 388 BRINNEL UNITS), USED ON USSR RAILROADS

Quench hardening of rails is the most important measure used in USSR for increasing the efficiency of railroad tracks. The creation of the optimum microstructure of the carrying part of the rail is the determining factor. Uniform hardness is the only durability parameter which can be determined under production conditions. Methods of testing mechanical properties under stretching of samples, resistance to wear, resistance to cleavage fracture, fatigue strength, and residual stresses are discussed.
